APPLICATION NOTES
– RELAY OUTPUT CHANGE
To modify relay outputs from normally open (N.O.) to normally closed (N.C.)
Cut the route relevant to desired output as in below figure
N.B. After cutting the route remember to solder the indicated pads with a drop of tin!
– ANTENNA
For increasing the range of board connect a 17cm isolated wire of 1mm to terminal 2 (input of antenna). The best placement is
obtained by fixing the wire to the terminal and disposing it perpendicularly from board, on the same plane.
